VBScript Filter Function

The Filter function returns a zero-based array that contains a subset of a string array based on a filter criteria.

Note: If no matches of the value parameter are found, the Filter function will return an empty array.

Note: If the parameter inputstrings is Null or is NOT a one-dimensional array, an error will occur.
